TYPEWRITING' MACHINE.

Application filed Ianuary 4, 1923. Serial I'm-810,580.

This invention relates mainly to soundsubduing cushion-supports fortypewriting machines.

In carrying out the invention 111 one way,

5. I place upon the typewriter desk ortable four supports upon whichrestthe four rubher feet of the. typewriting machine, one

- the grating. The grating may consist of wires which are-stapled orotherwise firmly secured u on the top of the block, so as to afford a rm'su port for the typewriting machine. The b ock may have a eight ofabout one inch. When the rubber feet of the -typewriting machine restupon four gratings "of this character, nolse-producm say six or eightmeshes to t e inch, and the wires may be under original tension. In anyevent, the wei ht of the ty wrlting machine tensions t e wires, wh1c isapparently a factor in preventin the conversion of the desk top into asoun ing board.

The wire strands may extend over the top of the block, and the lattermay be provided with an annular cap or rectan ular frame which may bemade of wood an may cover all of the grating except the portion whichextends directly across the opening in the block. This-topframenot onlycovers the unsi htly borders of .the wires and the step es that holdthe'same down, but also serves as recesses or sockets into which therubber feet are caught so that the typewriting machine cannot 5 doaround .upon the desk top; the blocks being Keferably screwed down uponthe desk top fore the ca s are applied thereto.

en it IS desired t'o place the typewriting machine upon a swinging leaf,such as used in a common type of typewriter desks, springs may be empoyed, one at each side of the machine, for holding down the frontportion of the ty writing machine upon the front noise-sub uin supportsabove described. The top on of the spring may be connected to the upperportion of the front column of the machine frame at each side, and thespring may extend down along said column, and'vat its lower end may becaught into the wine grating. By this means the front of theimachine isheld against tipping upwardl or rearwardly when the leaf is swung ownand back into the desk. The

caps on the blocks hold the typewriting machine from s'lidin down theeaf when the latter is rearwar ly inclined. The weight of the machine issuflicient to prevent the rear end of the typewriter from jumping out ofthe sockets or cups.

Whenit is'desired to support a typewriter desk or a sewing machine standor the like upon the floor, in a manner to avoid a,

sounding-board effect of the floor itself, similar blocks may be usedwith similar wire gratings thereon; but the may be made of ar erproportions accor g to the burden to e borne. Such blocks need notnecessarily be screwed to'a fioorpnor is it necessary to hold down thedesk or stands by wire springs. Similar supports may be used underpianos, phonographs and other musical instruments or apparatus where itis desired to prevent transmission of vibration from the instrument tothe floor.

Other features and advantages will hereinafter appear.

In the accompanying drawings,

Figure 1 is a view in side elevation, showing a machine in place uponthe support of the present invention.

Figure 2 is a perspective view of the support for one of the feet ofthemachine.

Figure 3 shows a modified form of one of the devices for anchoring themachine to the support.

On a platform 10, which may be the drop I leaf of a typewriter desk, arefour blocks 11, one for each footof the ty writing machine. The blocks11 are ho low, as indicated at 12, and the blocks and the hollows.therein may be of any desired shape. Set at each edge upon the top ofthe blocks and spanning the hollows therein are strings,

preferably of metal wire and preferably interwoven in the form of meshes13. These are shown as taut and as having the wires which com ose thesame soldered at the points 14 w are they cross one another. Set uponeach block and over the edge of the meshwork or grating thereon is aplate 15' no I *bottom of the platform, through the blocks and the ormeansof attachment for the's ring to the buckle .17,-or by staples, orin any other suitable manner,'the meshwork is held in place and undertension on the block between the same and the plate or annulus 15; Theblocks are preferably; anchoredto the platform 10, and for this purposebolts 18, having their heads 19 in countersinks 20in the extend upwardplates 15 andare secured by nuts 21.

As shown in Figure l," the feet 22 of the 1 machine 23 are set up themeshworks clear of the blocks and of the plates 15. For holding themachine on its support, when the latter is a dropleaf, springs 24 areprovided" at the front of themachine; These springs are under tension,and at their lower ends are caught in the meshes adjacent the frontcorner posts 25 of the machine. They extend vertically upward and havetheir upper ends caught on the framework of the ma chine. In Figure 1the upper end of the spring is shown as caught in an opening 26, whichis found in the upper part of the side plate of the frame of anUnderwood typewriting machine. Any other suitable place machine may beprovided. As ereinbefore stated, the springs 24 will hold the forwardpart of the machine to itss'upport when thedrop-leaf is swung into thedesk, and the weight of the machine will act to hold the rear portionthereof on the support. The

off the supporting blocks when the dropleaf is tilted, and to preventaccidental dis placement of the -machine from the supporting blocks atother times.

Instead of the springs 24, other means for.

holding the machine to the support may be provided. In Figure 3. adevice for this" place the machine may be tightened down upon thesupports.

Variations may beresorted to within the scope of the invention, andportions of the The books 28 are' threaded into and connected by aturn-' 29, so that after the hooks are in g thus. described.- myinvention, I v 'claimr 1.-As a new article of manufacture, a sounddeadening base block to be used as a support for the foot of atypewriter or like apparatus, said block being hollowed out v.andcovered with an integral meshwork superposed on the block, and meansupon said meshwork and around the hollowed portion of the block forholding the meshwork to. the block, said means extending into the blockto hold the parts in assembled relation.

'2. As a new article of manufacture, a sound deadening base block to beused as a support for the foot of a typewriter or like apparatus, saidblock being hollowed out and covered with a meshwork of wire strandssuperposed on the block, a cap on the meshwork and extending around thehollowed'portion of the block for preventing displacement of atypewriter foot andior holding the meshwork to the block.

3. A sound deadening base block to be used as a support for the foot ofa typewriter or like sound emitting apparatus,

said block being hollowed out and covered extended across its top.

I 4; Supporting means for a typewriter or other sound emitting machinethat has a plurality of feet comprising a tiltable support, a'base'block for ,plates or annuli .15 serve as abutments for the feet toprevent the machine from slidingeach foot on which said foot is adapt-ed to rest, each block being hollowedou't and covered with meshwork.means extending above and around each of the meshworks to prevent therespective feet from sliding off the meshwork, and means extendingthrough each block for holding the block to the support.

5. Supporting means for a typewriter or other sound emitting machinehaving a plurality of supports or feet, said means comprising a tiltablesupport, a base block for each foot on which said foot is adapted torest, each block being hollowed out and covered with meshwork, a capextending above and around the meshwork to prevent the displacement ofthe feet relative to the support, means for holding the cap to the blockand the block to the support, and

means attached to the typewriter and sup port to hold the typewriter onthe blocks when said support 15 tilted.
